1/14 Re: deep blue thread yesterday. I actually met the designer of deep
blue, Feng-Hsiung Hsu, a couple of times because he's a friend
of my wife's family. People just call him "deep blue". :-) After
he left IBM, VCs started throwing money in his direction for his
startup. Not sure what happened to his company. -taiwanese guy
\_ my summary of this thread:
<DEAD>www.ucomics.com/foxtrot/2004/01/13<DEAD>
\_ Luddite!
\_ I've read up on some URLs. The Deep Blue team was allowed to
modify the program between games in the tournament. These
modifications were made with the help of human grandmasters.
Deep Blue didn't beat Kasparov. Rather, Deep Blue with between-
game tweaking by human grandmasters beat Kasparov. That closes
the issue in my book. (That Kasparov went nuts and was incorrect
in suggesting that Deep Blue was being modified during the game
doesn't change the main point.)
\_ Yes, but Kasparov consults (quite frequently) with fellow
grandmasters during (when recessed) and between games. He also
employs computers to look for variations. So the resources
available to the Deep Blue team are available to Kasparov.
Similarly between games Fischer would consult others for advise
and modify his tactics according to past games. So it's not really
fair to say that the Deep Blue team can't modify the program
to reflect what essentially amounts to learning. A human tweaks
himself between games, so why can't a computer program be
tweaked in between games?
\_ wait a second. he talks to grandmasters *during* games? how can
that be? that's like chess by committee. I think you're wrong
there. Or else grandmasters advising Deep Blue would be ok.
\_ You could even argue that Deep Blue was "talking with
other grandmasters and improving its strategy" between games,
just like Kasparov could do the same. But while it
sounds appealing, I'm kind of uneasy about this reasoning.
\_ I think it would be better if neither side could do any out
side consulting or tweaking.
My gut feeling was that Kasparov was alone here, and
the corporate resources of IBM way outmatched him in the
between-game improvements.
\_ Well in the end the machine played by itself each game. Being
tweaked before and after games doesn't really change that. GK
made some mistakes too. It's not like they would know what
Kasparov would do in the next game.
\_ Some would argue that the engine was so tweaked to play
Kasparov, that it wasn't a general engine, but rather a "beat
Kasparov" engine. We'll never know, since it didn'y play
anyone else.
\_ That's true for any world-class chess player preparing
the issue in my book.
for a match. Such a player would spend a lot of time
optimizing his play for his opponent by studying his games,
preparing tailored opening surprises, etc. -- ilyas |
